New smart bra unhooks when it detects true love
Every woman has her own way of making sure a date doesn't go further than she wants.
Some girls don't shave their legs before the big night, while others can now use a new smart bra.
It only unlocks when the woman wearing it is in love.
The Japanese bra uses sensors and an app to analyze the user's heartbeat.
Makers say the app is able to distinguish between activities ranging from jogging to flirting.
When the wearer of the bra reaches a threshold identified as "true love," the clasp pops open, which could make for some awkward mements if it happens in the middle of a restaurant dinner date.
